Undefined Ids

Hello,

I've generated a C++ Parser and C++ Scanner with bison 2.3 and flex
2.5.33 respectively.
They are both prefixed with smt in my case. I've been also having a
hard time to use both together without trouble and unfortunately, no
example using C++ parsers and scanners exist, since it seems that
those which use a c++ scanner use a c parser and those which use a c++
parser, use a c scanner.

However, now while trying to compile my program I get:
smtlib-lexer.cc: In function 'smt::smt_parser::token::yytokentype
smtlex(smt::smt_parser::semantic_type*, smt::location*,
ParserDriver&)':

in this scope
smtlib-lexer.cc:782: error: 'yylloc' was not declared in this scope

along with some more errors related to these.
Problem is that yy should be smt in this case, right? By inspecting
the generated files I cannot even guess where these should be defined.
Any hints on where to look for a solution or suggestions would bee
greatly appreciated.
